GERD Clinical Trial
Official title:
Comparison of the Percentage Chronic on-Demand Users Treated With 20 Mg Pantoprazole on-Demand and Placebo o.d Versus Placebo on-Demand and 20 Mg Pantoprazole o.d. After Symptom Relief With 20 Mg Pantoprazole o.d.
The purpose of this study is to investigate several aspects of chronic use of acid suppressing medication: dependence on maintenance therapy, the possibilities for on-demand use, and predictors (patient characteristics) for daily need, for on-demand use and for termination of chronic use.
2-5% of the general population is chronic user of acid suppressing medication (proton pump
inhibitors, H2 receptor antagonists), mostly because of gastro-oesophageal reflux disease
(GORD). Prescription data from health insurances show that the number of chronic users
increases every year, which has large economic consequences.
There are indications however that on-demand and intermittent therapy can be as effective as
daily use. No evidence exists regarding patients who are likely to benefit from
intermittent, on-demand therapy or even termination.
In this study several aspects of chronic use of acid suppressive therapy are investigated in
family practice patients.
Chronic users are transferred to pantoprazole 20 mg for 4 weeks. Patients with adequate
relief of symptoms are randomized in two groups for a period of 13 weeks.
group 1: daily pantoprazole 20 mg, placebo on-demand (indicative for placebo-dependency)
group 2: daily placebo, pantoprazole 20 mg on-demand (indicative for pharmacological
dependency) Patients visit the research nurse at the beginning of the study and at week 4,
5, 10 and 17.
In this study we are looking for patient characteristics indicative for the dependency on
acid suppressive drugs and for possibilities to reduce the dose of these drugs.
Furthermore, aspects described in "secondary outcomes" will be addressed.
